To Arnt Gulbrandsen:
You stated that users are worrying less on the messages' appearance and
more on the overall experience of email, be that protection from scams
or better email client features.
I would like to point out that your position and the post on Campaign
Monitor are not mutually exclusive points. Of course users want to open
their inbox and be able to see a visually coherent email as originally
designed. Likewise, I am sure marketers are wont to steer clear of any
mis-renderings in their campaign messages that make it to users inboxes.
A few bad emails could be thrown away by their potential client, forcing
them thereafter to mentally note the marketer's messages as 'junk', or
worse, opt out of the messages entirely.
The goals of better user protection and better message rendering are but
two parts of the greater goal of increasing the effectiveness of the
email experience, and both goals are obstacles we need to accommodate
when necessary and eventually overcome when prudent.
